In this plant care guide, we want to show you how you care for the poinsettias correctly so your plant doesn’t just barely survives till Christmas but thrives year long and for years to come.

We gonna highlight absolutely everything you need and want to know about the Poinsettia care. Buckle up and enjoy the ride.

We start off with the most essential point. The Poinsettia care guide:


Poinsettia Care Guide


Poinsettia care requires frequent waterings and bright indirect light

Poinsettia care requires frequent waterings and bright indirect light



Poinsettia care requires loose and well-draining soil. You can either buy a premium potting soil or mix your own. We compiled an article about how to mix your own potting soil that is well-draining.

Very important elements of well-draining soils are chunky bits such as perlite, pumice or orchid bark. They loosen up the soil and ensure necessary airflow to the roots to prevent root rot.



This is a light hungry plant. Poinsettia care requires at least 6 hours of bright indirect sunlight. Therefore keep your plant in a spot where it gets vast amounts of bright indirect light.

If you cannot provide natural sunlight, Poinsettia care can also be successful with sufficient artificial light. A good grow light will do just as well.



The right time to water your Poinsettia is when the soil feels dry. The best option is to check this using your fingers. Stick your index finger into the soil. If it feels almost dry to the touch to about 1 inch into the soil, it is time to water.

In most homes, you will have to water Poinsettias about once a week to get the Poinsettia care right. This is a general rule of thumb as the location, the soil and pot you use as well as the environment play an essential role. They will define how often you will have to water.

The best advice is to keep the soil slightly damp but never soggy for your Poinsettia.



The best temperature for Poinsettia is between 65 to 70 degrees Fahrenheit (18°C-21°C) at daytime. Temperatures can drop at night to about 60 to 65 degrees Fahrenheit (16°C-18°C). 

If temperatures are too high it will cause the leaves to yellow and wilt and fall off. In addition, the beautiful coloured bracts that surround the flowers will fade.



Poinsettia care requires humid conditions. An option would be to spray the leaves daily. Poinsettias will survive without you spraying the leaves every day.

However, if you want to offer the best possible conditions, increased humidity is a must. An alternative is to provide a pebble tray below the pot that you fill with water.



Use an all-purpose water-soluble fertilizer. Water plants thoroughly after using any kind of fertilizer. Be it a water-soluble one or a dry slow-release fertilizer which is also fine. Recommended ratios for NPK fertilizers (Nitrogen (N), Phosphorus (P) and Potassium (K)) are 15-0-15, 15-16-17 or 20-10-20.

Fertilize once every 30 days and use the fertilizer at half-strength. This is generally recommended for houseplants and also holds true for a Poinsettia. 

If you want to get to know more about fertilization, you can read our fertilizer guide if you want to know more about what, when and how to fertilize your houseplants best.



To propagate a Poinsettia plant it is best to cut it back first and let new growth develop. Wait for the new growth to reach several inches before taking stem cuttings. At about a length of 4 inches, you can start to take cuttings. 

Make sure your cuttings have several leaves. 3-4 leaves are recommended on a good cutting as this will increase the chance of successful propagation.

Leaves will help the Poinsettia to conduct photosynthesis and will, therefore, provide energy for the cuttings to start the rooting process.

It wouldn’t be a Plantophiles Plant Care Guide if we wouldn’t have addressed the proper propagation in our Poinsettia care article.


Poinsettia Propagation

Poinsettia Propagation



Poinsettia can grow big very big. Did you know that the beautiful looking plant most of us buy around Christmas can reach a size up to 16 feet?

Yes, you heard that right. Poinsettia is native to Mexico and Central America and will grow to the size of a tree in its natural habitat.

By the end of May, the growth should start to skyrocket if the conditions are right and you are taking care of your Poinsettia all year round. 



We recommend removing the Poinsettia plants directly from the pot they come with. Remove the soil and plant your plant in fresh potting mix.

Because only if you are using your own pot and potting mix you can make sure that you are dealing with good quality materials and ingredients. To cut costs, Poinsettias often come with cheap soil and plastic pots. 

Good drainage is essential. Use a pot that has drainage holes. A common Poinsettia care problem is root and stem rot. Cheap and heavy soil will soak too much and becomes soggy. 


Poinsettia Care Year-Round

If you follow our Poinsettia care guide, you can take care of your Poinsettias all year round. There are just too many Poinsettias that are thrown away and almost all of us are guilty. 

The saddest pictures are seen in the garden centres were the leftover Poinsettias are either left to rot and die or are reduced in price drastically. Once Christmas is over, no one seems to be interested in Poinsettias anymore. At least until the next Christmas season starts.

Well, things can be different, as of course, Poinsettia care can be an all-year-round joy.


Poinsettia Care in Spring

If your carry-on caring for your Poinsettia into spring, make sure you are providing sufficient light as the plant loves bright indirect light. In Autumn and specifically winter the natural sunlight available is limited due to shorter days.

In early Spring the hours of sunshine are just about to increase so the right spot with bright indirect light for your Poinsettia is key.

In addition, early Spring will have colder temperatures leading to the heating running for multiple hours. As the Poinsettia loves humid temperatures you should make sure that it is not in front of a heating unit. It also prefers milder temperatures in general.
